Window air conditioners are designed to cool single rooms or fewer rooms at a time with enough BTU power. They are self-contained appliances that are comprised of components that are required to cool an area in a single tidy package. Traditionally, the window air conditioners are usually installed inside double-hung windows. But there are models on the market that can fit very well inside a wall opening that is sized appropriately. They have become so popular because they are inexpensive and they do not take any floor space in your home since they sit on the windowsill.
Unlike central air conditioning and split air systems, installing window air conditioners is very easy. You do not necessarily need a professional to do it for you and you can install them in less than an hour. Since they are usually installed in a semi-permanent fashion, only you will need to do is set them and forget about them. You will not need to wheel them around from room to room like portable AC units since they have been designed to stay put.
When shopping for the right window air conditioner, one of the things you need to consider is its cooling capacity. The cooling power of the air conditioner is usually measured in British Thermal Units (BTUs) per hour. A good window air conditioner that will provide you with good efficiency and effectiveness will have a BTU level that is designed to fit your space. You should avoid getting a window air conditioner with a very small BTU power since it is going to run continuously in order to try to cool a larger space and as a result your energy budget will shoot up. A very large window AC will also not be too good because it will not dehumidify and cool your space evenly, and as a result some areas of your room will either be uncomfortably hot or cold.
You will also need to take into consideration the electrical requirements of the window air conditioners. Since they are more powerful compared to other common household appliances, you will need to ensure that the electrical needs of your existing system are at par with the electrical requirements of the unit. Ideal window air conditioners operate on 115, 125 or 220 volt circuits. The electrical requirements include voltage, watts and amps and they are usually listed in the specifications of the units.
Another thing you need to consider when installing windows air conditioners is energy efficiency. Generally, window ACs are more economical compared to central ACs. They are cheap, and if you choose the correct size for your room, they will cost you less to operate in the long run. To determine the efficiency of a particular unit, check out for an energy star rating as well as an EER number in the product’s specifications. The energy star rated window ACs use less energy compared to the traditional models.
